Answer 1

Answer: about 65% of the total seniors own a driving license.

Answer 2

14) 268

Explanation:

Number of Seniors Seniors with Driving License Year

341 222 2014

367 240 2015

309 199 2016

382 246 2017

Question 13)

If we observe, we can find that the ratio of seniors with driving license to number of seniors is almost the same in all 4 years.

For year 2014:

`(222)/(341)=0.651\approx65\%`

For year 2015:

`(240)/(367)=0.654\approx65\%`

For year 2016:

`(199)/(309)=0.644\approx65\%`

For year 2017:

`(246)/(382)=0.644\approx65\%`

So, about 65% of the total seniors own a driving license.

Question 14)

In 2018, there were 413 total seniors. So around 65% of 413 would own a driving license.

65% of 413 = 0.65 x 413 = 268 (rounded to nearest integer)

So, in the class of 2018, 268 seniors will have the driving license.
